If it's in great shape physically / cosmetically, I'd have it completely restored. I have a SX-1250 that's been completely restored, and I think it's an awesome piece of hardware.
Pioneer SX-1050: worth repairing?
My Pioneer SX-1050 will cost about $350 to repair; one of the channels is shot. Is it worth it? Will it cover my Audio Physic Virgos? Its rated at 120 watts/channel. The Pioneer SX series have superb FM sensitivity; my old SX 750 can pick up college stations from my Boston suburban home; 3 high end tuners couldnt.
